Lots of folks write programs that don't have functions, programs that don't start from a template #!/usr/bin/perl --
use strict;
use warnings;
Main( @ARGV );
exit( 0 );
...
This is typical for short programs and one-offs
And you can't beat perl lanse :)
$ echo hi there | perl -lanse " print qq{$greet\t$F[1]}" -- -greet=by
+e
bye there
$ echo hi there > stuff
$ perl -lanse " print qq{$greet\t$F[1]}" -- -greet=bye stuff
bye there
These types of programs can live and do good work quite for a long time before they need a second look, or functions/modules/tests...
Code doesn't need to go places :)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
